Narrative:

A KC135 was handed off from east radar to west radar on a heading of 210; inbound for the airport requesting ILS approach to runway xxl. I was training a developmental who accepted the hand off and turned the aircraft to a heading of 220. At that same time there was a B212 helicopter maneuvering in the southeast practice area. The developmental instructed the B212 to fly no further west than their present position. There was no response from the helicopter. The KC135 advised that he had traffic at his 12 o'clock and five miles same altitude. The developmental told the KC135 that the aircraft was a helicopter and would maneuver no further west then his present position. The KC135 advised that he was climbing for traffic. The helicopter reported the KC135 in sight when the aircraft were 2 miles and 700 ft apart. The helicopter was told to maintain visual separation from the KC135. The helicopter did not respond.
